ACCLIMATION OF CHLOROPHENOL-DEGRATING ANAEROBIC SLUDGE AND THE KINETICS OF CHLOROPHENOL DEGRADATION DURING THE ACCLIMATION PERIODS
厌氧污泥降解氯酚的驯化及其在驯化过程中的降解动力学

Laboratory scale semi-continuous acclimation experiments of different kinds of anaerobic sludges and chlorophenols were conducted and the results are as follows: The anaerobic sludges acclimated to chlorophenols were characterized and the elimination of the lag period appeared in the process of chlorophenol utilization; The degrading activities of sludges acclimated to chlorophenols were related to activity and microbial consortia in primary anaerobic sludges, the relative ease of acclimation to PCP or 2-CP indicated that organisms existing in primary anaerobic sludge possessed the genetic capability for degrading PCP or 2-CP and that the acclimation procedure was satisfactory for their environment within the biomass. Addition of easily degradable organic substrate stimulated dechloronating degradation of chlorophenols in adapted-sludge. The kinetics of the degradation were constructed during anaerobic sludge acclimated to chlorophenols.
